Next we move to the more general cases. We will continue with the above simple and natural convention: the physical degrees of freedom on an extremal surface that characterize its corresponding SS state have only two basic states, \(\left| 1 \right\rangle \)  and \(\left| 0 \right\rangle \) . This is similar to the case in holographic tensor networks, where the state corresponding to an RT surface is defined as the direct product state of \(n\)  bonds cut off by the surface. Assigning each bond a Hilbert space dimension \(J\) , the Von Neumann entropy corresponding to the extremal surface is given by [1]}, [2]}
\(S = n \cdot {\ln _2}J.\)
